Throughout BFB, Basketball and Golf Ball often seemed to get on each others nerve, starting when Basketball helped 8-Ball become the new team leader. After 8-Ball gives up his leadership role and later gets eliminated, Basketball and Golf Ball were on better terms. However, "What Do You Think of Roleplay?" seemingly sparked a one-sided, ongoing grudge from Golf Ball to Basketball.
